摘要 目的研究口服热休克蛋白60(HSP60)对动脉粥样硬化(AS)大鼠血清基质金属蛋白酶-9(MMP-9)含量的影响。方法40只4周龄健康雄性SD大鼠,体重100g±10g。随机分为4组:健康对照组(C组),动脉粥样硬化未干预组(AS组),造AS模型前口服HSP60组(H1组),造模后口服HSP60组(H2组),每组10只。采用高脂饲料造AS模型,于大鼠180日龄时采血后处死,ELISA法检测各组血清中MMP-9含量。结果 C组、AS组、H1组、H2组大鼠MMP-9含量分别为:0.46μg/mL±0.19μg/mL,3.90μg/mL±0.75μg/mL,0.93μg/mL±0.23μg/mL,1.94μg/mL±0.73μg/mL。结论动脉粥样硬化大鼠血清MMP-9含量较正常对照组增强,口服HSP60能降低血清MMP-9含量,对维持纤维斑块稳定性有一定作用,且越早口服HSP60效果越好。
